Be on the lookout for lesser celandine!
Lesser celandine emerges in early spring, thriving in moist, lowland environments including forest floors, riverbanks and floodplains. It is also hardy enough to spread into lawns and other upland areas. It rapidly spreads via bulbils and tubers outcompeting native spring ephemerals.
Experts in nearly all Midwest states cite lesser celandine as a priority plant of concern (https://mipn.org/prevent-detect/ ). Below is a list of resources to help you learn more about this plant, including where it has been detected and how to identify, report, and control it.
